Within this article, the supply chain of solar power plants is delineated based on various parameters. The quantities of power plants and solar panels are determined by different priorities, such as investment levels, pollution mitigation, and reduction of gas consumption by conventional power plants, utilizing the particle swarm algorithm for optimal outcomes. The proposed model addresses uncertainties related to electricity demand, solar radiation levels, and consequently, the power production of solar panels, through the application of type 2 fuzzy logic. The optimization of the model is done keeping in mind various constraints including the supply of electricity and the maximum allowed use of solar cells. The innovation of this article is in the design of the supply chain model from the point of view of the uncertainty of electric power production and the amount of consumer demand and the optimal selection of solar panels for solar power plants to minimize the electricity consumption of the gas power plant and the amount of pollution caused by it. Based on the results obtained from the simulation of this article, it has been shown that considering the maximum investment capacity, up to 76 % of the electric energy can be supplied by building five solar power plants at certain distances from the electric substations around the case study. Considering the maximum weight coefficients for CO₂ plant emissions and gas consumption, five solar power plants are the optimal number that is achieved by proposed algorithm.

This stochastic model is aimed at generating the optimum schedules for various dispatchable generating resources such as micro-turbines, fuel cells, utility grid, energy storage devices as per the availability of the various VRE resources to meet the uncertain demand for a day-to-day microgrid operation. Further, a suitable scenario reduction approach named hybrid distance and similarity (HDS) approach is proposed to cater for two diverse objectives i.e., minimization of the Manhattan distance and maximization of the similarity index between an optimal scenario pair for generating a reduced scenario set by eliminating large redundant scenarios from its original large set. To verify the effectiveness of the proposed HDS, its performance is compared with three well developed distinct methods such as SBR (simultaneous backward reduction method), FFS (fast forward selection method), and SIMCOR (similarity-correlation method) on two different stochastic optimization problems including one real-life economic microgrid problem. All the competing scenario reduction methods are compared in terms of various performance indices i.e. OSDI (Output Sample Deviation Index), PSRI (Percentage Scenario Reduction Index), objective values, and computation time to verify their suitability and effectiveness on complex optimization problems. The proposed HDS method is found to be capable in achieving the lowest OSDI value of 5.68 at 98 % scenario reduction while compared to other competing methods i.e. 12.95 by SBR, 14.76 by FFS, and 16.32 by SIMCOR for the real-life microgrid problem. Moreover, the proposed HDS methods also outperforms the other three competing methods in terms of their objective function values after 98 % scenario reduction with a least computation time burden i.e. 87.6 %, 1.11 %, and 53 % less computing times are needed by HDS, FFS, and SIMCOR, respectively. These comprehensive simulation results reveal that the proposed HDS method is capable to generate high-quality scenarios, better approximation, superior stability, and with lower computation time burden as compared to the other three competing scenario reduction approaches.</div></div>","PeriodicalId":100488,"journal":{"name":"e-Prime - Advances in Electrical Engineering, Electronics and Energy","volume":"11 ","pages":"Article 100905"},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diabetic Retinopathy (DR) grading is crucial for the timely diagnosis and treatment of this common complication of diabetes, which can lead to blindness if left untreated. Existing methods for DR grading often need more accuracy and efficiency due to challenges such as variations in image quality, subtle lesion features, and imbalanced datasets. Furthermore, existing DR grading methods have exhibited lower security properties due to the need for image encryption algorithms in the IoMT environment. A Secure DR Grading Network (SDRG-Net) is proposed to address these issues, integrating several advanced techniques. Firstly, preprocessing techniques are applied to normalize the EyePACS and Messidor datasets and prepare the images for subsequent analysis. Next, Multi Level Color Transformation (MLCT) based image encryption is employed to enhance the robustness and security of the data, ensuring patient privacy while maintaining diagnostic accuracy. The encrypted images are then fed into an Iterative Convolutional Neural Network (ICNN) architecture for feature extraction, leveraging deep learning capabilities to learn discriminative features from the retinal images automatically. This step enables the model to capture intricate patterns and abnormalities indicative of DR. Furthermore precisely, an Improved Red Deer Optimization (IRDO) algorithm is introduced for feature selection, which iteratively refines the feature space to retain the most informative features while discarding redundant or noisy ones. This enhances the efficiency and interpretability of the model, leading to improved performance in DR grading. Finally, a Bagging classifier is employed for classification, leveraging ensemble learning to combine multiple base classifiers trained on different subsets of the data.
